I wanted to use the CSS pseudoelement :before for manipulating input elements. I had <input class="before-test"/>, and I wanted to use CSS to add a label before the element on small screens only (on a larger screen I would have a table with the label as the <th> element). So

  .before-test:before { content: "label: "; }

<div class="before-test"><input/></div>

With the selector targeting the enclosing element.
